Multiprotocol Service Layer

The Multiprotocol Service Layer (MPSL) is a set of libraries that provide common services for single and multiprotocol implementations.

The libraries are available as soft-float, softfp-float, and hard-float builds for the nRF52, nRF54H and nRF54L Series and as a soft-float build for the nRF53 Series.

These libraries provide the following key features:

  • Timeslot. It allows the application to schedule its own events concurrently with other protocols.

  • TX Power control. It provides an API for setting the maximum TX power per channel.

  • Clock control. It provides an API for configuring and controlling the low and high-frequency clock.

  • FEM. It provides an API for controlling external Front-End Modules.

  • SoC Temperature. It provides an API for obtaining the temperature measured on the SoC.

  • Short-Range External Radio Coexistence. It provides an API that allows the application to interface with several types of packet traffic arbiters (PTAs).

To enable MPSL in nRF Connect SDK applications, use the CONFIG_MPSL Kconfig option.
